Yes. And every energetic photon that hits that particle has the possibility of dissociating an atom from it. Most won't, but it's a process that will occur. High energy charged particles even more so.neufer wrote:For blue supergiants with luminosities a million times the Sun (but masses only 100 times that of the Sun) the radiation pressure exceeds the gravitational attraction by a factor of 10,000 for 1 µm dust grains. A 1 µm dust grain sitting one light year from such a blue supergiant could be pushed out to two light years in about 10,000 years.
